Abe Nakamaro pondered: "You mean burnt lime?" ”

"Exactly, for sterilization." Junichiro Takaki gestured.

"Go back and try, burnt lime is available in my country, why is it called quicklime?" Abe Nakamaro is not very accustomed to the problem of symmetry.

"Because it can also be turned into mature lime, it has the same use in some ways and different uses in some ways." Junichiro Takaki learned a lot from the newspaper.

"I wonder if I can learn how to make exchange vouchers and use them to print money." Abe Nakamaro knows what a voucher is.

Nominally called an exchange voucher, it is actually currency.

In fact, he was most worried that the people were unwilling to use copper coins, and there were many small countries in the country.

Some places do not produce copper, and Pingchengjing mints copper coins, and people elsewhere decide that copper coins are useless.

Talking about how much something is worth, it is not as good as looking at it yourself.

With ten eggs, how much rice or cloth can be exchanged for oneself, you know in your heart.

Ten eggs are exchanged for a few copper coins, what should I do if I can't buy those rice and cloth with copper coins?

The things you get in your hands are what you need, you don't need copper, and you can't eat or wear copper.

Then I thought of a way to allow people with officials to use money to get promoted.

Officials save their own money, which must be copper coins, donate a sum of money, and give it to different officials according to how much.

If there is no official, donate 5,000 copper coins to an official.

Officials also paid with copper money, and let them buy things with copper money.

However, it can only be circulated in Pyeongseongkyo and Gyeonggi Province, and people from outside still don't want it.

Abe Nakamaro and the others couldn't figure it out, because of what? The people of the Tang Dynasty like to use copper coins, and there are also those who make evil money.

Changing to your own country, what's the difference?

With a stomach full of doubts, everyone continued to visit the East Market.

Feel the prosperity of Datang and envy the life of the people of Datang Jingzhao Mansion.

There are so many things on the market that they can be described as varied.

The people took out the money, found the money, and even the blind used exchange vouchers to buy things.

There are blind spots on the vouchers, which are added in the same way as creating watermarks, and the blind spots are different for different denominations.

According to the feel and size of the voucher, as long as it is new, the blind can distinguish it.

In terms of specific purchases, there is no need for blind people to distinguish, and there are enthusiastic people next to them to help.

When a seller encounters a blind person, he not only does not dare to give the bad one, but also picks the good one and gives a little more, for fear that someone will report to the official.

"This big brother, the stall owner is good, I will give you two more dollars of meat." The envoys of the Japanese kingdom watched a man help a blind man and watched to buy things.

The extra two coins are also weight, and the money of ten coins and one tael is not the face value of copper coins.

"Eh, hey, hey!" The blind man carefully carried the money he had recovered, picked up the meat, and left with a stick.

Immediately, a well-wisher followed, helping the thirty-something-year-old to go home.

The envoys of the Japanese State sighed at the folk customs of the Jingzhao Mansion of the Tang Dynasty, and when they saw the fried dumplings being sold, they took out two copper coins from their sleeves.

He walked over and handed over the copper coin: "Bring me a roll." ”

The stall owner looked at the money he took and carefully discerned: "Don't sell, don't know." ”

"My Japanese money is the same as that of Datang Kaiyuan Tongbao." The next way is really ready to signal the other party to look.

The stall owner shook his head: "Then don't do it, it doesn't feel like Kaiyuan Tongbao is heavy." ”

"I'll add one penny, and three pennies will be worth two. I am an envoy of Japan. "I'm really depressed in the next way, and I made up another copper coin.

"Japanese envoys can't buy things and give less money, unless you are the proprietor of Li, I will give it away for nothing." The stall owner said as he took it and weighed it a few times.

nodded: "I sold you, no matter how you say it, you are all Japanese envoys." ”

After speaking, he put away the money and motioned to the woman next to him to give Xia Daozhen a roll of steamed buns with raw edge paper.

The woman carefully chose one and handed it to the next man, who looked relatively large and weighed the weight of the noodles.

I'm really in a good mood for the next road.,This looks big.。

He broke off one and put it in his mouth to bite into it, which was crispy.

Fujiwara Mayo next to him followed and pinched down one: "I really envy that their money can be spent anywhere." ”

"Li Yi is resourceful, maybe he knows what the reason is, and he can solve my domestic worries." Junichiro Takaki came up with a solution.

It is said that when the prime minister encounters difficulties, he will go to Li's Zhuangzi to seek advice, and the students from Li's Zhuangzi have done well in the county and village.

Explain that the master has the ability, ask yourself why the copper money in Japan can't be circulated, Li Yi can give an idea?

……

Bi Gou is already helping Junichiro Takashu to ask, the envoys of the Japanese State have entered the Tang Dynasty, in addition to the tribute things, there are also a large number of Japanese products.

Including silver, silver was used in the manufacture and in the same kaiju, and later it was canceled due to the lack of silver.

Datang's silver is less than gold, and no major mines have been found.

Silver was a luxury item in the Tang Dynasty and was used to make copper mirrors and jewelry.

A copper mirror with a little silver added is similar to a glass mirror, but it is easy to wipe the silver away.

"Do you want to collect their taxes?" Bi Gou carefully stood at the door of a workshop, watching Li Yi operate.

Li Yi is making litmus test paper, which is now a key step, and no one is allowed to disturb him.

After Bi Gou finished speaking, Li Yi turned his head and glared at him, and Bi Gou quickly shut up.

"I have sulfuric acid and caustic soda here, and if something goes wrong, it's over. Wait a minute. ”

Li Yi continued to operate, adding sulfuric acid is a red test strip, which is used to measure alkali; The second type is added with caustic soda to measure acid.

People always rely on experience to see the pH of the soil will be wrong, Li Yi took the time to collect litmus, after two days of processing, today the finished product.

When it's dry, it's ready to use, but he needs a control, and he'll have to mix it himself.

Half an hour, the craftsmen who learned understood it.

Li Yi breathed a sigh of relief, walked out, and asked the craftsmen to make a large number of them, and they would collect them when the litmus was not enough.

Limus is now a medicine, it is easier to find, it is not valuable, and children can pick a lot with a small shovel.

"With test strips, people have more choices when farming, and they can easily know what kind of land they have, what they need to add to neutralize, or what kind of crops to plant."

Li Yi has a small bamboo chip in his hand, and two litmus test papers are placed on it.

"Chemistry, huh?" Bi Gou didn't understand the principle at all, but he knew that this knowledge was not trivial.

"Yes, and if I don't say it, no one will make it for hundreds of years."

Li Yi was not modest at all, and he didn't plan to teach the litmus test to outsiders.

He would sell test strips and comparison charts for the imperial court to buy.

"Do you want to give it to the people?" As soon as Bi Gou heard that it had something to do with farming, he thought that Li Yi was sent.

"The imperial court pays for a pack of a hundred pieces, plus two comparison tables, in case one of them is lost or broken, there is a backup.

The government took it and sent it to the people, and the people went to see their own fields, and then took the table that came back to the yamen and compared.

A pack of twenty dollars, if you don't need a comparison table in the future, nineteen dollars, you are optimistic about it. ”

Li Yidu has planned it, selling money, and farming is what the imperial court should manage.

"Oh no, how much does this thing cost you?" Bi Gou refused, he thought that he would suffer a loss if he bought it.

"Lao Bi, don't always think about the cost of materials, you don't consider the cost of technology? I was frugal, and after hundreds of thousands of attempts, I invented ......"

"The old man doesn't believe it, you should have made it directly, and failed once or twice at most." Bi Gou still refused.
